R&T and RoninMoto, If you are going to do a RTW, DO IT NOW!You want me to repeat that? DO IT NOW! Don't be like me. I got out of college in 1965 and thought about roaming around the world for a couple of years. I was brought up on the philosophy of getting a job, working hard, save your money and when you retire, then it's time to play. Only one problem with that thought. Now I'm retired. It's time to play. I have the money but my right knee is gone. I just got out of a total knee replacement surgery a couple of weeks ago and the idea of a long ride anywhere is totally out of the question. The rest of my body is in good condition but standing on the pegs floating over the bumps for extended time is only a dream. Ruff, all I can say is DO IT NOW. The back roads of the world are a magnet you should follow. If this sounds like the ramblings of a cynical old man, the answer is yes.
Yours truly, old fart Bob

It is common for people to get a bit depressed after surgery. But, sitting around wishing for lost youth is a big waste of your remaining life. Knee rehab is tough. Get tougher and get your life back.
